Super or wonder metals are fictional metals which possess unnatural physical properties beyond any that are currently known and are frequently used as plot enabling devices within science fiction and fantasy stories, role playing games, and video games. The properties of such metals usually include some or all of the following:

According to the X-Men movies adamantium can be shaped when created (by the combination of fluid ingredients). However, once cooled to a solid state, it becomes indestructible once again. Through Magneto's effects on Wolverine's adamantium skeleton, it can also be established that adamantium is a magnetized alloy. The Forgotten Realms setting of D&D makes frequent reference to this material.

Arenak and inoson are both transparent, super-hardened treatments of ordinary metals which appear in Edward E. Smith's The Skylark of Space and its sequels, some of the first fiction featuring interstellar travel.

This is the metal utilized to construct the eponymous Super Robot of the anime series Mazinger Z. In the series, Chogokin Z is created from the newly-discovered element Japanium. Other variant metals include Chogokin New-Z, used to construct Great Mazinger, and Chogokin New-Zα, which was the basis material for Mazinkaiser. The series' sequel Grendizer features an unrelated but still highly similar metal called Space Alloy Gren.

The term "chogokin" has since become a trademarked name for toys and models manufactured in Japan by Bandai. It is also informally and frequently used by collectors to describe toys with high die-cast metal content, or in a nostalgic sense toward those earlier Super Robot series and toys.

A metal used in the TV series Digimon. a Digital World metal created from the mineral Chrondigizoit. It is commonly used by Metal-species Digimon, as it is the strongest metal in the Digital World, and is vulnerable only to the strongest of attacks and other Chrome Digizoid. Despite being a metal, it is flexible enough to be used for constructing wings. Certain beings also attained sentience due to their Chrome Digizoid composition. Many Digimon incorporate it in their weapons or armor, and it can even be grafted directly to the user's body. While the basic form is quite strong on its own, it is possible to refine it into five chromatic variations with unique abilities. These refined alloys can then be hybridized into even more powerful forms.

In the Doctor WhoTV show, this is the material from which the Daleks craft their nearly indestructible battle shells. The metal is considered a bonded polycarbide, and was dubbed "dalekanium" by the human Dortmun in The Dalek Invasion of Earth. Later it is seen that the Daleks call the material by this term.

Duralloy Armor is the sixth strongest type of armor in the Master of Orion series.

Duralloy is also featured in some role-playing games, namely Metamorphosis Alpha and Gamma World. In both of these games, Duralloy has properties vary similar to Adamantium from the Marvel Universe. In Gamma World, Duralloy can also be found in special containment drums, that maintains it in a molten state by a magnetic field. Once the seal is broken, the liquid metal must be used quickly (about a minute) before it cools down and becomes permanently solid. The cool down is rapid, and absorbs background heat.

Durasteel is one of the most used alloys in the Star Wars universe. Its qualities include: being very flexible, resistant to heat and cold, monumentally physically stress resistant, and the color brown. Because of these it is the most common material for the manufacture of spacecraft hulls.

Durium was an ultra-strong, extremely dense, infusible sapphire blue alloy of made from resistium and other "ultra-elements" (which had an atomic structure consisting of a nucleus of "negatrons," orbital protons and without any electrons present in the atom at all), in The Infinite Atom by John W. Campbell, Jr.Durium would also be featured in several of the later works of E.E. "Doc" Smith.

Etherium is a magical blue-grey metal that is incorporated into beings starting at a young age. It appears in the Esper shard in the Shards of Alara subsequence in the Magic: the Gathering Multiverse. Etherium also makes an appearance in the film Laputa: Castle in the Sky, directed by Hayao Miyazaki.

This is an isotope of iridium, with one second of direct exposure equivalent to a lethal dose. (A reading of 3217.89 Rads/hr is recorded from fifty feet away).[1] The blade of St. Michael's Sword, from Riptide was forged from this material. In real life Iridium 80 is impossible as all known isotopes have over 164 nucleons.

This is a super metal from J. R. R. Tolkien's Middle-earth universe. It is precious and silvery, stronger than steel but much lighter in weight. It first appears in The Hobbit, where it is also called "silver-steel". Its properties were developed in The Lord of the Rings.

A rare super-heavy metal, which is one of the most prized substances in the Stargate universe. It can be used to make weapons of mass destruction, or produce near infinite clean energy in the form of the naquadah fusion generator, and forms the basis of most civilizations technologies. In its refined state it forms a quartz like substance with superconductive properties, capable of storing vast amounts of energy.

In Warhammer 40,000, the Necrons utilize a material called necrodermis (which translates into "Corpse Skin"), a metal that heals itself, for everything, including their own bodies. The "living metal" was used, in particular, to create the slow moving tomb ships which were able to carry the Necrons through space to colonize various foreign worlds. Additionally, necrodermis was capable of being formed into bodies which the C'tan, a formless energy mass, could inhabit.

In the DC Universe, it is native to Thanagar, the home planet of Katar Hol and Shayera Thal, the Silver Age Hawkman and Hawkwoman. Among the unusual properties of Nth metal is the ability to negate gravity, allowing a person wearing an object, such as a belt, made of Nth metal to fly. In addition, Nth metal also protects the wearer from the elements and speeds the healing of wounds, increases their strength, and protects them from extremes in temperature. It has many other properties that have yet to be revealed in full. In the future, members of the Legion of Super Heroes wear flight rings made of an alloy of Nth metal called Valorium.

A dark, dense, magical metal from the Discworld novels. Not only is it rare, but it is also naturally imbued with magical power. In its unrefined state it produces high levels of thaumatic radiation. The great bell of Unseen University, which is constructed of octiron, produces negative sound when struck, and other unforeseen results often accompany octiron's use. The molten core of the Discworld is thought to be composed of Octiron giving rise to the strong magical field of the disc. As seen by how compass needles are constructed with octiron, the metal is highly attracted to such magical fields.

A ferroalloy of the Marvel Comics universe which is stronger than titanium though weaker than adamantium. There is also a form of omnium which possess elastic ductility while retaining high durability, which was somehow employed in a full-body epidermal supplantation procedure on the villainous character Warhawk.

A reddish metal mentioned in several ancient writings, most notably Plato'sCritias dialogue. Orichalcum was considered second only to gold in value, and could be mined in many parts of ancient Atlantis. By the time of Critias, however, it was known only by name. It is used to make structures, walls, and coins, and may perhaps be based on an actual mineral or gold/copper alloy, possibly Auricupride.

In sources of modern media however the metal has acquired much more wonderful qualities. In the Indiana Jones adventure game it is used to power the machinery in Atlantis, while in the Exalted setting orichalcum is the strongest of the five magical materials and can be created by distilling mundane gold using Gaia's blood (Magma) and concentrated sunlight.

It also appears in several video games—occasionally spelled orichalcon—usually as a material better than "ordinary" mithril. In Final Fantasy for the Nintendo Entertainment System the party of heroes comes across orichalcum as a versatile but incredibly powerful sword. Although of fairly high attack power and accuracy it can unexpectedly be used by ninjas, thieves, and black wizards.

In Ehud Gat's Lilith: Operation Genesis, ProtoZortium was an alloy of metal that was partially grafted unto biological matters (proteins, possibly). The matter was 20 times more resilient than steel and could partially deflect beam weapons (such as lasers). being quasi-alive, dents and holes would regenerate over time. The super-metal was used for armors of ships and the likes but could also be laced into the bones of a human subject to form a bond that turn the bones nearly indestructible.

Radium X was an intensively radioactive extraterrestrial element discovered by Dr. Janos Rukh (Boris Karloff) in the 1936 film the The Invisible Ray. In the film, Dr. Rukh creates a death beam projector which harnesses the incredible power of Radium X for use as a destructive weapon of mass terror. Interestingly, Radium X also had healing powers. In a memorable scene, Rukh restores the sight of his blind mother (Violet Kemble Cooper) with the Radium X projector after developing a filter to curb its destructive effects. According to legend, this scene inspired John Lawrence (the younger brother of physicist Ernest Lawrence) to use radiation on his mother—who had been diagnosed with inoperable cancer of the uterus.[2]

The "hydrogen" of the "ultra-elements" (which had an atomic structure consisting of a nucleus of "negatrons," orbital protons and without any electrons present in the atom at all), resistium was many times stronger than steel or titanium and had unique chemical and electromagnetic properties. First featured in The Incredible Planet by John W. Campbell, Jr.

In Larry Niven'sRingworld, this metal[citation needed][improper synthesis?] forms both the walls and floors of the Ringworld. It is milky-gray translucent, and nearly frictionless. A fairly thin layer of scrith is capable of blocking 40% of the neutrinos that encounter it, equivalent to almost a light year of lead. It also absorbs, in near entirety, all other radiation and subatomic particles, and it rapidly dissipates heat. The tensile strength of scrith is similar to the strong nuclear force, with the Ringworld foundation only about 30m deep. Additionally, it is transparent to large magnetic fields.

Enormously strong: scrith is impervious to most weapons, and even such a force as most comets or asteroids. In order to bypass this, Ringworld engineers used a device called the cziltang brone to pass from spaceports, through the scrith, to the Ringworld.

Scrith is said to have been artificially produced through the transmutation of matter.

In the Matthew Reilly novel, Temple, thyrium is an extremely dense extraterrestrial metal that is native to a binary star system called the Pleiades [really an open star cluster, also known as the Seven Sisters but it does contain a binary star system called HD-23642] and found on Earth only from meteorites. Thyrium bears a striking resemblance to the radioactive terrestrial elements Plutonium and Uranium but because it is denser it takes fractionally less mass of it to produce the same amount of energy as a larger piece of Uranium. Thyrium also burns with 100% efficiency leaving no contaminated waste byproducts, unlike the Terrestrial element Uranium which creates waste that must be discarded in radioactive rods. A particular isotope thyrium-261 is the core element of a thermonuclear device called a Supernova, which is capable of destroying almost a third of the Earth's mass causing the Earth to spin out of orbit and into space.

In the Halo series, Titanium-A Armor is composed of a high-grade Titanium-50 alloy, specially strengthened at the molecular level. Titanium-A has numerous uses throughout the UNSC due largely to titanium being lightweight and extremely strong, with a high tolerance to heat. It took new found importance after the beginning of the Human-Covenant War; To contend with the Covenant's plasma weaponry, Humans needed armor that would withstand the heat of the directed plasma. Despite its strength and resistance to heat, the Titanium-A plating is usually boiled away within seconds, and does not effectively dissipate the plasma. Its primary use is as armor for ships. UNSC Frigates have sixty centimeters of plating on their hull, and UNSC Destroyers have up to two meters of plating. Larger ships were known to have even more, such as ten meters to a supercarrier. The UNSC uses Titanium-A for construction of bases as well, to make them less susceptible to destruction. Places such as HIGHCOM Facility Bravo-6, CASTLE Base and Camp Hathcock used Titanium-A armor in their superstructures.

In the scene in which Scotty provided the formula for transparent aluminum on a Mac computer, the diagram showed an alloy of aluminum, silver and oxygen in an approximate chemical formula of Al306Ag2. A real-life development of transparent aluminum is ALON, or aluminum oxynitride, that has an approximate chemical formula of Al23027N5.

In Star Trek, spacecraft hulls are made from the super metal alloys duranium and tritanium.

Lilith: Operation Genesis defines it as CuAst2Ti3 (or Copper Distroidium TriTitanium), an industrial alloy using a fictional element (Astroidium, allegedly mined in the asteroid belt). Defined as "lustrous silvery", tritanium is completely impervious to all forms of energy currents.
Tritanium Armor is also the third strongest type of armor in the Master of Orion series.

The material from which the ship Virgil was constructed in the film The Core. The word unobtanium is also colloquially used by engineers to describe non-existent materials with desirable mechanical properties ("That shaft would have to be made of unobtanium in order to carry such a high load"). Unobtanium is also featured in the movie Avatar, as it is that metal's worth at $20M a kilo (because of its properties as a superconductor at room temperature), which motivates the unnamed company.

A unnamed super dense metal in Battlefield Earth by L. Ron Hubbard that mixed with certain other elements causes an uncontrollable fission process that continues until there is nothing left of a planet except light gases. This metal is supposed to occur in meteorites before they burn up in an atmosphere.

The Predator race, called Yautja, of the Predator films, as well as the humanoid aliens from AVP, use a super-light metal that can be forged to a monomolecular edge. Such an edge would be impossible with any nonfictional element, none currently known that provide such a strong molecular bonding. Yautjavian weapons thus work on the principle that the thinner the cutting edge the more keen the weapon, this metal allowing for impossibly sharp blades. Often this metal is layered for greater strength, as when made into Yautjavian plate armor.

An extremely hard super metal used to armor starships in the Master of Orion PC games series. According to Master of Orion II: Battle at Antares, it is 4 times as strong as titanium (based on game statistics) which quadruples the ship's durability in relation to the standard titanium combat armors.
